ALL  INTAKE MANIFOLD - Part Number 6233
Manifold "C" Accessories Series. 1 in Offset Riser (Used in place of No. 6229 on late Courier Mazda OHC engines where cam cover is wider than cylinder head side surface. Also fit Mini-cars. The "C" series 2 barrels come standard to accept the Holley 5200 series carbs. In most cases a one inch spacer No. 6229 will be necessary to that this type carb linkage can clear the manifold. The Holley Model 2300 two barrel requires a carb adapter No. 6231 in order to fit the "C" Series 2 barrel manifolds. This is recommended for competition only. A universal linkage accessory Kit No. 6230 is also available for cable operated applications/ conversions. Offy has developed a "C" series of competition style high performance manifolds to fit the void between absolute street performance and modified street/race applications. These manifolds have been designed to accept larger carbs of a performance variety because the plenum and runners of the manifold have been opened up to carry the hgh volume flow required by modified enignes at higher RPM's. These manifolds come with stock emission provision for those vehicles which might be used as modified street/race. Vehicles used in race only may block off these provisions as necessary. The "C" series Offy open plenum design really boosts engine characteristics and greatly improves the torque in mid to higher RPM's. The torque range of these manifolds has been designed to fit into street modifed and competition RPM requirements of the 4 and 6 cylinder engines. Depending on the size carb and engine type, the "C' series manifold has a fantastic range from approximately 2500 RPM delivering great performance thru 7000 + RPM. Naturally, the larger the carb ,the higher the RPM range will be. All 4 cylinder, 2bbl "C" series manifolds are drilled to accept the two stage holley Model 5200 series carbs. In most cases a one inch spacer No. 6229 will be necessary so that this type carb linkage can clear the manifold. The Holley Model 2300 two barrel requires a carb adapter No. 6231 in order to fit the "C" Series 2 barrel manifolds. This is recommended for competition only. A universal linkage accessory kit No. 6230 is also available for cable operated applications/conversion. "CW" Series. 1 in Offset Riser. (Used in place of No. 6239 on late Courier/Mazda OHC engines where cam cover is wider than cylinder head side surface). Also fit Mini-cars. The "C" Series for the Weber 32/36 mut be ordered as "CW". A Weber riser plate No. 6239 is included with the "CW" to ensure linkage clearance. A universal linkage accessory kit is also available for cable operated applications/ conversions. Offy has developed a "C" series of comptition style high performance manifolds to fit the void between absolute street performance and modified street/race applications. These manifolds have been designed to accept larger carbs of a performance variety because the plenum and runners of hte manifold have been opened up to caryy the hgh volume flow reuqired by modified enignes at higher RPM's. These manifolds come with stock emission provision for those vehicles which might be used as modified street/race. Vehices used in race only may block off these provisions as necessary.
